1. BOSS Audio Systems R1100M Riot Series Car Audio Subwoofer Amplifier - 1100 High

• Class a/b topology - class a amplifiers have enormous amount of current flowing through its output transistors with no audio signal. class b amplifiers have no current flowing through its outputs with no audio signal
• Specs - dimensions: 9.13 x 10.44 x 2.25, weight: 4.43 lbs., speaker impedance: 2 to 8 ohm, thd @ rms output: 0.01%, s/n ratio: 102 db, frequency response: 9 hz to 50 khz, fuse quantity: 1 30 amp ato blade
• Switchable bass boost - bass boost allows you to adjust the low bass within the boost range to just the way you like it
• Low & high level inputs - a low level (rca) input is measured in voltages. a high level (+/- wire) input is measured in wattages. both essentially carry signal from your receiver to your amplifier to your speakers
• Power - 1100 max x 1 @ 2 ohms, 550 max x 1 @ 4 ohms
• Mosfet power supply - a mosfet is an electrical switch that allows the flow of electrical current. it controls the output voltage & current precisely by removing the output current sensing loss & eliminating all secondary feedback circuitry

2. BOSS Audio OX3KD Class D Car Amplifier – 3000 Watts, 1 Ohm Stable

• Power: 3000 watts max x 1 @1-ohm, 1500 watts max x 1 @2-ohms. dimensions: the ox3kd is 12.3 inches in depth, 7 inches in width and 2.3 inches in height. it weighs 6.5 lbs.
• Warranty: boss audio systems provides a powerful 6 year platinum online dealer warranty so long as the purchase is made through amazon.com. we strongly encourage professional installation of this product to ensure proper and safe functionality
• Strapping capable: you are able to strap two ox3kd amplifiers and double the power that is being sent to your subwoofer(s). you now have the ability to connect more subwoofers to take advantage of the extra power
• Class d: power loss is significantly reduced making the amplifier highly efficient. excess energy is stored until its needed instead of being converted into heat. reduction in size/weight, reduced power waste, smaller heat sink, compact circuitry
• 1 ohm stable: able to continuously power loads of 1 ohm without encountering difficulties such as overheating. typically made to power up subwoofers that demand the heavier power load requirements to be able to perform the way they were made to

3. Planet Audio PL3000.1D Class D Car Amplifier - 3000 Watts, 1 Ohm Stable

• Strapping capable - you are able to strap two pl3000.1d amplifiers and double the power that is being sent to your subwoofer(s). you now have the ability to connect more subwoofers to take advantage of the extra power
• Variable low-pass crossover - subwoofers reproduce sound based on a number of different low-range frequencies. you can set exact sound specifications for the bass frequency reproduction
• Class d - power loss is significantly reduced making the amplifier highly efficient. excess energy is stored until its needed instead of being converted into heat. reduction in size/weight, reduced power waste, smaller heat sink, compact circuitry
• Specs - dimensions: 11.9 x 7 x 2.3, weight 6.7 lbs.
• 1 ohm stable - able to continuously power loads of 1 ohm without encountering difficulties such as overheating. typically made to power up subwoofers that demand the heavier power load requirements to be able to perform the way they were made to

4. Planet Audio TR4000.1D Class D Car Amplifier - 4000 Watts, 1 Ohm Stable

• Power - 4000 watts max x 1 @1-ohm, 2000 watts max x 1 @2-ohms
• Variable subsonic filter - to prevent your subwoofer(s) from bottoming out, the variable subsonic filter filters out frequencies below the subwoofer(s) specified low frequency limits and allows the driver to reach a maximum safe excursion
• 1 ohm stable - able to continuously power loads of 1 ohm without encountering difficulties such as overheating. typically made to power up subwoofers that demand the heavier power load requirements to be able to perform the way they were made to
• Class d - power loss is significantly reduced making the amplifier highly efficient. excess energy is stored until its needed instead of being converted into heat. reduction in size/weight, reduced power waste, smaller heat sink, compact circuitry
